f Toclltckom itmayconcev'n: Be it known. that I, WILLIAM BEARD, a citizenlof the United Eitates,v residing at Salida, in the county. of Chaifee and State of Colorado, have invented certain new and useful Improvements in Internal-Combus tion Engines; and I do declare the followingto bea full,-clear, and exact descrip- 3 tion of the invention, such as will enable i others skilled in the art to which it appertains to make and usethe same. v

My invention relates to improvements in internal" combustion engines and more particularly to those of the'four cycle type.

i r The objectgof 'theinvention is to provide simple means wherein a greater amountof mixture may besup'p ied to the various linders than the amount which they obtain y "drawing in theirown charges of mixture on the desce'nt of their istons, i

a i In carrying out the a ove end, I provide the crank, case of the motor with-a numlqer of air tight compartments, provide each "of intakcsand air 'outleti valves, a manifold which leadsfromwthe air outlet valves to take manifold discharging into the inlet ,valve cages as is common in devices of this character, and a spray nozzle projecting ,froina suitablecarbureter into the air manifold.

i I, 'With the above and minor objects in view, the "invention: resides in certaip novel features of construction and combination herein described and claimedanti shown in the drawings wherein:- i

shown my improved engine as comprising in general, a sectional crank case 1, a p ir independent air intake and air outlet valve-:3: 3 aud t in to the compartments formed h the partitions, a plurality of cylinders "a, pistons 6 in the cylinders, a crank shaft '3 connections between the pistons and crank shaft, intake valves 1 8,: into th... upper ends of the cylinders, exhaust valves 9, therefrom, an inlet manifold 33?,

an air manifold 11 which communicates with the cages of the valves 4, an upright.

tube 12 connecting the manifolds-10 and 11 y and a carbureter 13 having a nozzle dis charging .into said tube 12. addition to the elements sofa!- hriefly set forth, the invention ccntemplatescertain other features It inafter described. a As above stated, the crank case "1 is of sectional formation, and its upper section ftarrics the cages 14 and 15 for the air inlet 'nd outlet valves 3 and 4 respectively.

hese cages may be of any appropriate for-- iationbut are preferably so constructed s to allow the valves 3 aud t tohe autoatically closed by means of suitable springs. As clearly shown in Figs. 3' and" 4, the cages 15 are-here shown of" cylindrical formation having their upper ends prov A vided with outlet ports 16 which communicatewith the interior of the air manifold 11, the latter being'of suitable length and dimensions'and havin a boss 17 rising from its central portion an a similar boss 18 de'- 'to appear, the discharge nozzle 20 of the r carburetor 13, being disposed at" said con- .tracted ortion.

The P113612 is further providedwith a bypass 21 which communicates freely with the lower end of said pipe while its upper end communicates with the upper' portion of said pipe througha spring closed valve 22. The i e 12 is also provided with the usual .butte y valve 23 for controlling therlio amount of mixture passing therethrpu and into the cylinders. The inlet mdhifo d l0-is of common construction as. arkil likeawise the cages for the valves 8 and 9. Iti

expedient however that the valves, 8 be operated by mechanical means,' the necessityof this becoming apparent as the 'descrip tiou therewith, a needle valve 26 in said chamber 25 and operated by an appropriate float 27 within thev chal'mb'er 24,"said valve automaticall inlet port in th clover end of the carbureter thereby allowin the carbureter, when the that 27 lowers.

As cleai'ly show nk'in Fig". 3, the discharge nozzle 20 of the carbureter extends upwardly within the contracted portion 1'9 of the pipe 12, the supply of fuel-throughsaid nozzle being cut olf,"w-hen desired, by means ofa f needle valve .30, which is coarsely threaded throughone side of an integral neck which connects the float chamber 24 with the'tube or pipe 12. The outer end of the needle valve 30 passes revolubly through a stuiling box'and is provided with an operating lever "31, the latter being limitedjin its outward.

v latter being threaded into the interior of a movement by m'eansof a stop, 32 and carrying on its lower side, a short arm 33 which is connected by-means of a link 34Et'o a lever which ispivoted intermediate its ends to an arm which depends from a'screw plug 36, the

valve cage 37' which isrigidly secured to'the boss 18., The plug 3635 provided with a central opening having its upper portion formed into a'valve seat for the reception of a -conical valve 38 from which a stem '39 depends and 'has a pivotal connection with the inner end." of the lever Thusit will be seen that when the arm 31 is rocked for the purpose of causing the needle Valve 30 to. closethe outlet from the carburete'r, the

'linkj34t will push downwardly upon the" outer'end of the lever thus causing 'its inner end to move upwardly-to unseat the valve 38. A If now, any leakageshould occur through the nozzle 20, the fluid will be allowed to-escape and will not accumulate in the air manifold 11.

. In order that the needle .valve 30 be normally retracted until the arm 31 contacts spring, 41 which may be operated in any suitable manner.

Coming now more particularlyto details most clearly shown in Figs. 2 amid, the, crank case 1 is provided at its center, with i an upstanding bearing post '42 which ,car-

ries a suitable bearing 43 disposed in longi tudinal a-linement with bearings 44 carried by the partitions 2 and bearings 45' carried fuel to flow from a tank 28through ajva ved outlet tube 29 and intoment, the two'central cranks being raised are/here shown as standing in vertical aline-,

and the two .endmost being lowered. By

reference to these two figures, it will 'beseen that the partitions 2 divide the crank case'l 'into a central cmnparti'nent l7 andftwoend mosti compartments .*.l8 and thatfeaifi. comj partment is provided with'an aiiviu et valveop'emiig' and closing a fuel;

and an air outlet valveofi thejforms before] described.

With the ,parts as above described? (see Fig.2) the'operation of the" device is as follows: Thefpi'stons I and IV on theirde scent, have forced'charge of air fro n the compartments 48 pastthe fuel spray nozzle 20 and into the cylinder" above the piston I, this downward movement having been effected.by expanison'of the gases above the piston IV: the piston III, onjtsjascent', has scavenged itscylind'er'of burnt gases and the piston H'has compressed a charge of mi=x*- ture in its cylinder and now stands in position to have said charge ignited by the above piston II, the pistons I and IV will move upwardly thus'ompressing the gas nozzle 20 -and into the cylinder above the piston IIIWhICll, upon'lts ascent, will compress said gas to be fired. Thus it will be seen that the two compartments 48 feed the sparking meagns. VVhen said gas is ignited,

two endmost cylinders and that the central compartment, {equal involume to the two compartments 48, feeds. the two central cylinders and that this feeding occurs at proper intervals to force charges of mixturejjntw the intake cylinders. I i

It is to be note'd that by providing the above described connections between the needle valve 30" and the .valve' 38, the latter is automatically opened when the former is closed, thus preventing any fuel-accumulatingiwithin the ail-manifold 11 andthe pipe 12; This mechanism also becomes a'dvantageous when the motor-1s employed in con;

nection withan automobile. In this con-. nection, when the vehicle is running down grade, the above mentioned switch maybe actuated to break-the circuit of'the sparking .mechanisnrthereby automatically closing the K needle valve 30 and'opening the valve 38.

As the pistons continue topper-ate, theair forced out of the crank case, is now free to pass upwar'dly into thecylinders of the,

motor, thusefiectually'cooling' the same".

The: valve '38 being now open, the air, discharged from the crank case ,will flow through the opening normally closed by said valve, to 'a'certain extent; this blowingany if fuel which Ina 1. eage'37, entirelyout. I v v i i D'It mayhere' be further explained that the by-pass 2l v and its valve 22 are provided fo'r the purpose of regulating the amount of I I n time air which isfed to thd mixture before it jii entersthe cylinder. For this purpose, I

F 1 vhaveiprovijded a hollowi-screw722 which mflyieldingly, through the action of a coil 1 l thatithe amount of free air, fedto the'mixture, maybe varied. i a

v -i i In the figures of the drawings so, far delsjg scribed, it will be seen that I have provided jfthe correct amount of airto pass into the In FigSQSQIQand however, I have shown f; valvesj i flhje air inlet *valye inithis case 1 standsuprightwithits cdnical head 51 restjjinglnpon an appropriateseat formed in the 2 5 z 'lower side off a laterallyprojecting valve depending stem 53 which slides loosely lthroughfa boss 54;,which latter is carried g 10, the lower end of the boss 54: is tapered upon the stem '53 by means of asleeve 57 ,1clined downwardly from its periphery-to its center whileits upper end is provided with fanannularjfiange 58. i

Thus it contact' with the stem 53 at all times,the u -tension ofthe spring 59. acting not only to close the valves bui also to force the sleeve compensatingnfor any wear on the latter;

yplicatednt each air inlet from ithe interior" strugtion here is identical withtheconstruct10n shown in Fig. 10 with the exception As the remaining structure is identical-with that illustrated in Fig. 10,

I haveemployed the same reference numeralsthereon and if a furtherexplanatiom thereof is'required, the description of said Fig. 10 may be referred to. 7

From theforegoing description, taken in connectionwith the accompanying drawa ings, the salient features of the invention will be readily understood and it will be seen that I have produced an internal combustion engine of comparatively simple con;-

struction which will be highly efiicient 1n operation on account-of the increased VOl- =ume of explosive mixture which is fed to its 20 the manner in which I may well employ a lncam shaftfily for mechanicallyopening said siderable minuteness and have set forthcertain specific embodiments which may well a be employed for carrying out the objects of thevinvention. I do not however wish to be limited to details of construction or to any K minor details'other than as set forth in the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Let A four-cycle internl combustion engine comprising a pluralit of cylinders having independent intake valvesadapted to open only when the cylinders are free of burnt gases, an intake. manifold for supplying explosive'mixture to. said cylinders through I t y the intake valves thereof when the latter are 1' When thepartsare' in normal position. the

opened, a single tube projecting from said into said tube, an air manifold spaced from said intake manifold and communicating with said tube, a crank case with which the cylinders communicate at their inner ends,

j wardly andoutwardly in pairs, whereby all of the "air compressed by the descent of each 'pair of pistons may be forced past the fuel nozzleandinto the cylinder whose intake valve 18 open.
